Be it known that I, ALFRED GEORGE HUB- the King of Great Britain, residing at No. 28 Poplar Walk, Herne Hill, London, S. E. 24., England, have invented certain new and useful Improvements in Closures for Receptacles, of which the fol lowing is a specification.

This invention comprises improvements in and connected with closing means forcontainers and vessels, being particularly applicable to milk churns.

One object of the invention is to provide a closing meansof a simple nature, capable of withstanding rough usage, not costly to manufacture and capable of affording security against tampering with the contents of the container during transit.

A further object is to combine with tightening means carried upon a skirt or overhanging portion of the lid a locking means adapted for having locking engagement with co-operative means on the churn. In achieving this object, it is advantageous to provide the tightening means on the churn with the said co-operative locking means as will appear. Q. Yet another object is to provide a locking means on the lid adapted for being retained ina retracted position while the operation of tightening or loosening the lid takes place and for being automatically thrown into retracted position.

looking engagement when released from said Also to adapt said locking means for being sealed by means of a card or the like, so that the'locked churn cannotbe tampered with without the fact being disclosed. 1

These and other objects are achieved by the construction-s hereinafter described, by way of example, with reference to the accompanying drawings, the said constructions being capable of modificat on in various ways without departing from the essential features of the invention hereinafter c1aimed.

In the drawings v 1 Figure 1 is a vertical section through the upper part of a .churn'a nd .itslid or cover, these parts being constructed and fitted with tightening and locking means according to the present improvements.

According to the present improvements, and as shown in Figures 1 and 2, the churn is formed'or fitted around the neck-portion a with single or double short lengthsof inclined or helical ribs or threads I) and the lid 0 is-made conical in vertical section and furnished with a relatively rigid skirt 0. .The coned portion 0 of the lid isconveniently maderelatively flexible and is adapted to fit in a taper seating a at or nearthe top of the neck portion a of the churn.. As seen in Figure 1, the skirt portion consists of a flanged ring, the. flange 0 being at the top and inwardly turned and the lid proper consists of a dishedv sheet metal disc, the peripheral flange or-rim c of whichis suitably joined to thelflange 0 Furthermore. the

inner side oftheskirt e of the lid 0 is fitted withstuds or projections e and there is one setof studs 6 all round the skirt or there may betwoyset's of studs at different distances, from the, plane conta ning the bottom edgelof the skirt 0. The number of studs aroundfthe circle suitably correspondswith' the number of lengths of rib'or thread '12 disposed around the neck a ofthe churn, this number 7 being usually three,

There may be notches or gaps f, as shown in Figures 2 and 8, formed in a rim or bead a around the top of the churn so that, in presenting the lid to the churn, the studs 8 within the skirt 0 of the lid must first pass through respective notches, or gaps f, in order that the coned part c of the lid 0 may descend toits seating a. In this condition of the parts, each stud e of the lower set will be found just beneath the upper ex-i tremity of an inclined or helical rib b and each stud e of the upper set, if used,will be found just above such extremity, as seen in 3 Figure 2; If the lid 0 be now turned so that the studs 6 e approach respective ribs 7 orthreads b, the lower studs e will engage I the'under surface 6' ofthe ribs and-the lid 0 will be tightened on its seating a and by reversely turning the lid 0, theupper studs e will ride up the ribs Z) and the lid 0 will be loosened. Now the above described means of surface of a rib, or of each rib, b,flso that tightening the lid enables a very efiicient and simple locking means to be employed as will now appear. In the first place a locking rack b may be formed on the peripheral three surfaces of a rib b are utilized, namely, the lower surface I) of a rib for tightening, the upper surface 6 for loosening, and the peripheral surface 6 for locking. The lock or latch for engaging with the rack 72 is carried by the lid 0 and is convenientlyfitted in the'skirt portion 0, the bolt or tooth being operated byelastic meanswhich force it inwards into engagement with the outwardly projecting teeth 6 of the peripheral rackon a 'I'libb."

Referring to Figure 1, the upper-portionof the churn is formed with a conical part 02 and aframe' yon the exterior of the cone receives an address card or the like 2.- As

i g* or side of the frame or casing. thls pm g is fixed a wing-like will be seen, the frame 3 issecured so that the opening at the'top into which the" card is inserted is covered by the skirt 0'' when the lidis in position. It follows, therefore, that the card 2 cannot be withdrawn while the lid is in position-on the churn.

7 An advantageous construction of lock 7 p shown in Figures 1 to5, comprises a rectan- 50 7 ably secured in or over an aperture 9 in the gular framing or casing adapted to be suit skirt portion 0' of the lid 0. hFor example, thesaid frame may be rivett' d to the ring. Towards one vertical side of therectangular frame 9 a vertical pivotpin g is loosely mounted, the upper end of this pin-takingof the pivot pin 9 and the two ends 0 with a projection g on itsupper'edge, this projection being engaged by a spring h whichconstantly tends to force. the win -like latch g 'inwardly into engagement wit the teeth 79 of the rack t, For example, a

spring h may-be coiled around'thetop art the coil may project, one an upwardly inclined portion h, engaging by its extremlty wlth a part of the fixed frame or casing g and the other, a straight portlon k engaglng the said projection '9 The'lower edge of V the wingdike latch 9 may be formed a downwardly directed tooth or projection g which normally rests upon the floor or bottom member of the casing or frame 9,-

The arrangement is such that if theYfrfee f 7 end of the latch g be pulled out to disengage its tooth or projection fromthe rack-Z), the coiled part of the spring it, being in con1- pression, tends to depress the latch'g s'o that as soon as the bottom projection g of the a latch moves off the floor of the casing 92,

the latch is depressed by the spring hand the bottom projection g is then below 'the said floor level. The descentof the latch 9 causes the pivot pin 9 to project appreciably through the bottom frame member 9*. In thiscondition the latch 9 cannot be thrown by the spring into engagement with-the rack 6 because the' bottom projection g engaging the bottom 9* of the'caslng g,

acts as a stop to prevent this. In this condition of the latch 9 the lid 0 may befreely operated for looseningvor tightening. When it is desired to return the latchg? intolo'c k ing engagement, the downwardlyprojecting' end of the pivot pin 9 is pressedupwetrdl'y and thus lifts the latch g?" so that its bottom projection" g is raised. jnstfabove the'said floor level, whereupon the spring it throws the. 1atchg'. inwardly into-lockingengage ment with theirackb I I I i I The locking device 9 may be so contrlved that it is only possible to get at thelatch g towithdraw it by using a tool or' key device. of. particular construction, as for ex? ample'a' hook device '5 (see Figure 12) which canbe insented and the hooked enc't 'i'jen gaged with a free end of the-latch," Or it might be desirable to provide a' key, pin or the like device which c uIdQbeinserted to turn thawing-like latch. For example, it

is possible'to soarrange the latch that it can be released only, by V the vinserticm of a key for engaging with and turning the pivot pin 9 On the other hand,-the latch may be so fashioned as to be capable of being I withdrawnby a finger;

To'prevent the latch g from being it;

leased from the rackwithout disclosing'the fact, a sealing label or card may beinserted in a frame or recess in or onthefront of the casing g. F or example, and as shown" l' s e l y' s e car jm y be pressed into a circular frame Z after the manner of'the disc stoppers used on milk gage the card. It is now impossible to remove the card withoutmutilating it, as any attempt to withdraw the card is is resisted by the edges of the notches k engag-' ing the bent ends n of the springs 12. desired, instead of bending the ends of the springs, the latter may be fitted with pawllike teeth n Figure 9, the sloping portions of which permit the card 70' to be inserted and the horizontal portions engage the edges of the notches 10 when an attempt is made to withdraw the card.

In the modified construction of lid seen in Figure 13, the ring frame is of inverted trough section, being preferably made by stamping and pressing sheet metal, thesheet metal disc 0 being joined to a flange c of the ring which also comprises a cone part c and a skirt part c.

In Figure 14: all the parts of the lid aremade by pressing and stamping one single sheet of metal, thebo tto'm edge of the skirt being bent out for stiffening purposes.

In by means of a wire ring 0 enclosed in a pocket or tube formed by bending over the bottom edge 0 o It will be seen from the foregoing that a very effective and simple form of closing, tightening and locking meansis provided, involving the employment of very few working parts, none of which is liable to injury even when the churn is roughly handled as frequently happens. Also the parts are easily manufactured, are not costly, and do not create any difficulty in regard to maintaining the degree of cleanliness desirable. All these are important points when considering the transport of,

and protection against tampering with, a commodity such as milk.
